Description

The present invention relates to an automatic faucet device, and more particularly to an automatic faucet device that automatically spouts water and stops spouting water according to a detection state of a sensor.

Conventionally, an automatic faucet device that automatically discharges water when a detected object such as a human body is detected by a sensor is known (see, for example, Patent Document 1). In a hand-washing device to which such an automatic faucet device is applied, water (dirty water) containing dirt generated by hand washing flows into a bowl or a perforated plate, but a period during which water is not discharged from the automatic faucet device (that is, If the period in which the sensor does not detect the detected object continues for a long time, such dirt adheres to the bowl or the perforated plate in a dry state and adheres to the dirt, making it difficult to remove the dirt. In order to prevent this, it is preferable to perform water discharge again before the attached dirt dries and becomes fixed. For example, Patent Document 2 proposes a technique of detecting the presence of a human body and then discharging water from the sink cleaning port for a certain period of time after the human body is no longer detected, thereby maintaining the sink in a clean and clean state.

However, in the technique described in Patent Document 2, even if the faucet device has not been used before, when a person leaves the cooking table (strictly, when the person leaves the detection range of the sensor), the sink cleaning is performed. Water is discharged from the mouth, resulting in unnecessary water discharge. On the other hand, even if the faucet device was used before, if a person stays around the cooking table (strictly, stays within the detection range of the sensor), water is discharged from the sink cleaning port. Otherwise, the dirt becomes stuck and becomes difficult to remove.

Therefore, it is an object of the present invention to provide an automatic faucet device that can suppress wasteful spouting and can appropriately prevent dirt from becoming hard to remove due to dirt sticking to a bowl or the like.

<Overall structure>
First, FIG. 1 is a perspective view of a hand washing device to which an automatic water faucet device according to an embodiment of the present invention is applied, as viewed obliquely from above. As shown in FIG. 1, the handwasher 5 mainly includes an automatic faucet device 1 that automatically performs water spouting and water spouting depending on the detection state of a detected object such as a human body, and the automatic faucet device 1. And a bowl 3 for receiving the water discharged from the drain and draining it from a drain port (not shown).

<Structure of automatic faucet device>
Next, the details of the automatic faucet device according to the embodiment of the present invention will be described with reference to FIGS. 2 to 6.

FIG. 2 is a diagram for specifically explaining the configuration of the automatic faucet device according to the embodiment of the present invention. FIG. 2(A) is a perspective view of the automatic faucet device according to the embodiment of the present invention as seen obliquely from below, and FIG. 2(B) shows this automatic faucet device at IIB- in FIG. 2(A). It is sectional drawing seen along the IIB line. Here, the configuration near the water discharge part of the automatic faucet device 1 according to the present embodiment will be mainly described.

As shown in FIG. 2A, the automatic faucet device 1 has a water discharge pipe 11 which is a curved tubular member. As shown in FIG. 2(A) and FIG. 2(B), at the tip of this water discharge pipe 11, a first water discharge part 12 configured to perform foam water discharge from a first water discharge port 12a, A nozzle-shaped second water discharge part 13 configured to perform spray water discharge (in other words, mist water discharge) from the second water discharge port 13a, and a sensor 14 that detects an object to be detected, such as infrared rays, An LED (Light Emitting Diode) 15 that emits light is provided. Specifically, the sensor 14, the first water outlet 12a, the LED 15, and the second water outlet 13a are arranged in this order from the top to the bottom of the water outlet pipe 11. Further, inside the water discharge pipe 11, the first water discharge part 12 is connected to the first flow path 17 for supplying water to the first water discharge part 12, and the second water discharge part 13. A second flow path 18 that is connected and supplies water (including electrolyzed water described below) to the second water discharger 13 is provided.

Here, the first water discharger 12 mixes air with a filter as foam water discharge, and performs foam water discharge in which bubbles are included in the discharged water flow. The foam water discharge by the first water discharge unit 12 corresponds to the "first water discharge form" in the present invention. On the other hand, the second water discharger 13 is a sprayed water discharge so that the water spreads from the second water discharge outlet 13a at a predetermined angle, in other words, wider than the cross-sectional area (diameter) of the second water discharge outlet 13a. A fog-like water discharge is performed so that the water spreads over the area. The spray water discharge by the second water discharge portion 13 corresponds to the "second water discharge form" in the present invention. The second water discharger 13 sprays water at a flow rate lower than that of the first water discharger 12, and sprays water at a faster flow rate than the first water discharger 12. In one example, the 1st water spouting part 12 spouts water at 2 liters per minute, and the 2nd water spouting part 13 sprays water at 0.3 liters per minute.

Next, with reference to FIG. 3, the principle of spray water discharge of the second water discharger 13 according to the present embodiment will be described. FIG. 3 is a vertical cross-sectional view of the second water discharger 13 as seen along the flow direction of water.

As shown in FIG. 3, in the second water discharge part 13, the water flowing from the inflow port 13b provided at the upper end causes a straight flow (see an arrow A11) in the internal flow path 13d and the internal flow. A swirling flow (see arrow A12) is generated in the internal flow passage 13d by the water flowing in from the slit portion 13c formed on the outer peripheral surface of the upper end portion of the passage 13d. Due to such a synergistic effect of the straight flow and the swirling flow, the spray water is sprayed in a full cone shape from the one second water discharge port 13a at the lower end of the internal flow path 13d. Specifically, water is discharged in a range larger than the cross-sectional area (diameter) of the second water discharge port 13a. In this case, the water is spread and discharged from the second water discharge port 13a at the discharge angle θ. In the foam water discharge by the above-mentioned first water discharge part 12, since water is discharged in a range substantially the same as the cross-sectional area (diameter) of the first water discharge port 12a, the second water discharge port of the second water discharge part 13 is discharged. The discharge angle θ from 13a is larger than the discharge angle from the first water discharge port 12a of the first water discharge unit 12.

Next, the relationship between the water discharge range of the second water discharger 13 and the irradiation range of the LED 15 according to the present embodiment will be described with reference to FIG. FIG. 4 is a sectional view of the automatic faucet device 1 according to the present embodiment, which is similar to FIG. 2B.

As shown in FIG. 4, in the present embodiment, in order to inform the user of the water discharge range R11 of the water sprayed and discharged by the second water discharge part 13 by the light from the LED 15, the light irradiation range R12 by the LED 15 is The installation angle of the LED 15 and the irradiation range of the LED 15 are set so as to substantially match the water discharge range R11 by the second water discharger 13. For example, the LED 15 is arranged such that the central axis of the LED 15 is substantially parallel to the central axis of the second water discharger 13.

Next, with reference to FIG. 5, the positional relationship between the first water discharger 12, the second water discharger 13, and the sensor 14 according to the present embodiment will be described. FIG. 5 is a sectional view of the automatic faucet device 1 according to the present embodiment, which is similar to FIG. 2(B).

As shown in FIG. 5, in the present embodiment, the second water outlet 13a of the second water outlet 13 is disposed on the rear side of the first water outlet 12a of the first water outlet 12, and The water is prevented from dripping from the first spout 12a onto the second spout 13a. In this case, the second water outlet 13a of the second water outlet 13 is configured so that the water sprayed and discharged from the second water outlet 13a does not reach the first water outlet 12a of the first water outlet 12. It is arranged. In addition, the second water discharge port 13a of the second water discharge unit 13 is disposed so as to spray water toward the vicinity of the drainage port of the bowl 3 (not shown in FIG. 5). In addition, in the present embodiment, the sensor 14 is disposed above the second spout 13a of the second spouting portion 13 so that the sensor 14 can appropriately detect the hand even if the person does not reach so far. Is also arranged on the front side. In other words, the second water discharge port 13a is arranged rearward of the sensor 14. By doing so, the water sprayed and spouted from the second spout 13a is less likely to splash on the portion of the user's arm or body that should not be wetted.

Furthermore, in the present embodiment, the orientation relationship between the sensor 14 and the second water discharger 13 is set so that the sensor 14 does not detect water sprayed and discharged from the second water discharge outlet 13a of the second water discharger 13. It is adopted. Specifically, since the detection accuracy of the sensor 14 decreases as the distance from the sensor 14 increases, the directivity range R13 (the range including the detection range of the sensor 14) corresponding to the detection direction A23 related to the detection of the detected object by the sensor 14 (Specifically, it corresponds to a range in which the detection range is extended to the front), but the sensor 14 and the second water discharger 13 are arranged so as to intersect with the water discharge range R11 of the second water discharger 13 at a front side separated position. The orientation relationship with is adopted. More specifically, the sensor 14 is arranged so that the detection direction A23 of the sensor 14 faces away from the water discharge direction A22 of the second water discharge part 13. In other words, the line L13 (typically corresponding to the central axis of the sensor 14) along the detection direction A23 of the sensor 14 extends in the vertical direction from the center of the second water outlet 13a of the second water outlet 13. The sensor 14 is arranged so as not to intersect with the line L12 (typically corresponding to the central axis of the second water discharger 13) on the front side.

Further, in the present embodiment, the first water discharger 12 and the second water discharger 13 are configured so that the water sprayed and discharged from the second water discharge outlet 13a of the second water discharger 13 is less likely to fall on the user. The orientation relationship is adopted. Specifically, the first water spouting part 12 and the second water spouting part 12 are arranged so that the water spouting direction A21 of the first water spouting part 12 and the water spouting direction A22 of the second water spouting part 13 are directed away from each other. Each of the 13 is provided. In other words, a line L11 extending in the vertical direction from the center of the first water outlet 12a of the first water outlet 12 (typically corresponding to the central axis of the first water outlet 12) and the second water outlet The first water spouting portion 13 so as not to intersect with the line L12 (typically corresponding to the central axis of the second water spouting portion 13) extending vertically from the center of the second water spouting portion 13a of the first water spouting portion 13a. 12 and the 2nd water discharge part 13 are each arrange|positioned.

Next, the functional configuration of the automatic faucet device according to the embodiment of the present invention will be described with reference to FIG. 6. FIG. 6 is a block diagram schematically showing the functional configuration of the automatic faucet device according to the embodiment of the present invention.

The common flow passage 21 is supplied with normal water such as general tap water (city water) (herein, this water is appropriately referred to as “normal water” to distinguish it from electrolyzed water). To be done. On the common flow channel 21, a water stop plug 22 for blocking the flow of the normal water in the common flow channel 21, a filter 23 for removing foreign matters mixed with the normal water, and a flow rate on the secondary side in order from the upstream side. A constant flow valve 24 that keeps the flow rate constant is provided, and is branched into a first flow path 17 and a second flow path 18 at the downstream end of the common flow path 21.

The first flow path 17 is provided with a first electromagnetic valve 25 that opens and closes to switch between normal water flow and cutoff in the first flow path 17. When the first solenoid valve 25 is open, normal water flows through the first flow path 17 and the first water discharge part 12 connected to the downstream end of the first flow path 17 flows. Water is usually spouted.

On the other hand, the second flow path 18 is provided with a second electromagnetic valve 28, a pressure regulating valve 29, a safety valve 30, a check valve 35, and an electrolytic cell 37 in this order from the upstream side. The second solenoid valve 28 switches between normal water flow and cutoff in the second flow path 18 by opening and closing. When the second electromagnetic valve 28 is open, normal water flows through the second flow path 18 and the second water discharger 13 connected to the downstream end of the second flow path 18 discharges the water. Spray water is sprayed. The pressure regulating valve 29 is a valve that regulates the water pressure to a desired pressure (a pressure suitable for performing spray water discharge). The safety valve 30 is opened when the pressure in the second flow passage 18 becomes equal to or higher than a predetermined pressure (for example, when the pressure in the second flow passage 18 suddenly rises due to the second outlet 13a being blocked). Then, the water in the second flow path 18 is made to flow into the first flow path 17 via the bypass flow path 31 to reduce the pressure in the second flow path 18. The check valve 35 is a valve that prevents the reverse flow of water. When electrolyzed, the electrolyzer 37 electrolyzes normal water to generate electrolyzed water (this electrolyzer 37 corresponds to the “functional water generator” in the present invention). A filter may be further provided on the downstream side of the electrolytic cell 37.

Further, the automatic faucet device 1 further includes a controller 40 that controls the components inside the automatic faucet device 1 (this controller 40 corresponds to the “control unit” in the present invention). The controller 40 operates by the electric power from the AC power source 39, and supplies the electric power of the AC power source 39 to the sensor 14, the LED 15, the first electromagnetic valve 25, the second electromagnetic valve 28, and the electrolytic cell 37, respectively. Take control. Specifically, the controller 40 acquires a sensor signal indicating the detection state of the object to be detected by the sensor 14, and based on the sensor signal, controls to switch ON/OFF of the LED 15 and open/close the first solenoid valve 25. Is controlled, the control for switching the opening/closing of the second electromagnetic valve 28, and the control for switching the execution/stop of the generation of the electrolyzed water by the electrolyzer 37.

Here, the electrolyzed water produced by the electrolyzer 37 will be described.

The electrolyzed water used in the present embodiment may be any water that has a sterilizing function obtained by electrolysis. A typical example of electrolyzed water is electrolyzed water containing hypochlorous acid. In general, tap water or tap water contains chloride ions, so that free chlorine is generated by electrolysis. Free chlorine exists as hypochlorous acid (HClO) in an acidic state, and in this form, the bactericidal activity is about 10 times stronger than that of the hypochlorite ion (ClO ⁻ ) which is an alkaline existing form. Moreover, even if it is neutral, a strong bactericidal power intermediate to that can be obtained. Therefore, the water electrolyzed in the continuous electrolysis tank is sterilizing water having a strong sterilizing power.

As described above, commonly used tap water or tap water contains chloride ions, but when used in areas with low chloride ion concentrations or when strong bactericidal action is required, salt Chloride ions can be supplemented by adding chlorides such as.

As an electrode used for chlorine generation, a conductive base material carrying a chlorine generation catalyst or a conductive material comprising a chlorine generation catalyst is used. Depending on the type of catalyst for chlorine generation, for example, iron-based electrodes such as ferrite, palladium-based electrodes, ruthenium-based electrodes, iridium-based electrodes, platinum-based electrodes, ruthenium-tin-based electrodes, palladium-platinum-based electrodes, iridium-platinum-based electrodes. , Ruthenium-platinum-based electrodes, iridium-platinum-tantalum-based electrodes, and the like. The conductive base material carrying the chlorine generation catalyst is advantageous in terms of manufacturing cost because the base material part having a structure can be made of inexpensive materials such as titanium and stainless steel.

In addition to chlorine, it may be hypohalous acid obtained by electrolyzing water containing halogen ions.

Examples of other electrolyzed water include silver ion water obtained by using silver as an electrode. It is said that silver ions are adsorbed to an enzyme on the cell membrane of bacteria and inhibit the action of the enzyme, so that the bacteria cannot sustain life. It also has the effect of coating the surface of the base material that comes into contact with it, making it difficult for bacteria to propagate on the surface of the base material. Since silver ions coat the surface of the base material to prevent bacteria from adhering and have bactericidal activity, the growth of bacteria on the surface of the base material can be effectively suppressed. At that time, by combining with a cleaning method for increasing the replacement rate of the drain trap, it becomes possible to suppress slimy odor and odor of the drain port for a long period of time.

In addition, it is possible to use various kinds of electrolyzed water, such as ozone water that produces high concentration ozone as well as oxygen on the anode side, especially by using lead dioxide (β type) as an electrode for electrolysis. Is.

Furthermore, examples of the sterilized water other than the electrolyzed water include an aqueous solution in which various sterilized components are dissolved. The sterilizing component to be dissolved may be solid, liquid or gas. When using a liquid sterilizing component, for example, ethanol, alcohols such as isopropanol, hydrogen peroxide, or the like may be applied. When using a gas sterilizing component, ozone water may be produced by dissolving ozone in the form of fine bubbles in water, for example. When using a solid disinfecting component, for example, sodium hypochlorite may be applied.

The various sterilized water as described above corresponds to the "functional water" in the present invention. Here, in the present specification, the term "disinfection" means not only to reduce the number of bacteria (in this case, it includes not only the meaning of removing and reducing the bacteria but also killing and reducing the bacteria). It is used as a broad concept including the meaning of suppressing the growth of bacteria even if it is not reduced. The “functional water” in the present invention means water obtained by adding a sterilizing function in this sense to ordinary water by a predetermined treatment.
In the present embodiment, an example of using electrolyzed water as the functional water in the present invention will be described, but instead of electrolyzed water, it is also possible to use sterilized water as described above other than electrolyzed water. Needless to say.

<Control by controller>
Next, the control executed by the controller 40 in the embodiment of the present invention will be specifically described.

(First embodiment)
First, the control performed by the controller 40 in the first embodiment of the present invention will be described.

FIG. 7 is a time chart showing basic control according to the first embodiment of the present invention. FIG. 7 shows, in order from the top, the sensor signal supplied from the sensor 14 to the controller 40, the drive signal supplied from the controller 40 to the second solenoid valve 28, and the drive signal supplied from the controller 40 to the first solenoid valve 25. The signal, the drive signal supplied from the controller 40 to the electrolytic bath 37, and the drive signal supplied from the controller 40 to the LED 15 are shown.
The sensor signal is turned on when the sensor 14 detects the detected object, and turned off when the sensor 14 does not detect the detected object (hereinafter, the sensor signal is on. The state in which the object is being detected is called the "detection state", and the state in which the sensor signal is off and the sensor 14 is not detecting the object is called the "non-detection state". The drive signal of the second solenoid valve 28 corresponds to the open/closed state of the second solenoid valve 28, and the drive signal of the first solenoid valve 25 corresponds to the open/closed state of the first solenoid valve 25. However, the drive signal of the electrolytic bath 37 corresponds to ON/OFF of the electrolytic bath 37 (in other words, the operating/non-operating state of the electrolytic bath 37), and the drive signal of the LED 15 corresponds to the ON/OFF state of the LED 15. To do.

First, at time t11, the sensor signal switches from off to on, that is, the sensor 14 switches from the non-detection state to the detection state. At this time, the controller 40 energizes the first electromagnetic valve 25 to open the first electromagnetic valve 25, and causes the first water discharger 12 to normally spout water. This foam water discharge is water discharge for washing the user's hands and the like. In the following, water spouting performed for such a purpose will be appropriately referred to as “water spouting for hand washing” (note that the water spouting is not only for the purpose of washing hands, but also for washing the face, storing water in the bowl 3, washing toothbrushes, etc. Although it is used for various purposes such as doing, for the sake of convenience to distinguish it from the after-water discharge described later, the word "water discharge for hand wash" is used to represent hand washing. Then, at time t12, the sensor signal switches from on to off, that is, the sensor 14 switches from the detection state to the non-detection state. At this time, the controller 40 stops the energization of the first electromagnetic valve 25 and closes the first electromagnetic valve 25 to end the foam water discharge from the first water discharger 12, that is, the hand-wash water discharge. To finish.

After that, when the non-detection state of the sensor 14 continues for a predetermined time T1 from the time t12 when the foam spouting as the hand-washing spouting is finished, the controller 40 causes the second spouting section 13 to perform spray spouting. This spray water discharge is performed in order to prevent the dirt flowing out by hand washing using the above-mentioned water discharge for hand washing from being difficult to be removed by drying and adhering to the bowl 3 of the hand washing device 5 and the like. (Hereinafter, water spouting for such a purpose is appropriately referred to as "after water spouting" as water spouting performed after hand-washing water spouting). That is, after a predetermined time T1 has elapsed after the hand-washing water discharge is finished, spray water-jetting is performed as after-water discharge to wash away the dirt due to the hand-washing water discharge before it dries and becomes fixed. From this point of view, the predetermined time T1 is set based on the time until the dirt due to the water for hand washing is dried and fixed. For example, the predetermined time T1 is set to 3 seconds.

Specifically, the controller 40 first turns on the LED 15 at time t13 and irradiates the water discharge range R11 of the spray water discharged by the second water discharge section 13 with the light of the LED 15 (see FIG. 4). Notify the user that water will be discharged. Then, the controller 40 energizes the second electromagnetic valve 28 at a time t14 immediately after the time t13 (corresponding to a time after a predetermined time T1 has passed from the time t12 when the hand-washing water discharge is finished), and the second electromagnetic valve 28 is energized. The valve 28 is opened, and at time t15 immediately after this time t14, the electrolysis tank 37 is energized to generate electrolyzed water in the electrolysis tank 37, thereby spraying electrolyzed water from the second water discharge part 13. That is, after-water discharge is performed. In this manner, the energization of the second electromagnetic valve 28 and the electrolysis tank 37 are not performed simultaneously, and the energization of the electrolysis tank 37 is started after the energization of the second electromagnetic valve 28 is started. Since a large amount of power is consumed at the timing of switching the second solenoid valve 28 from closed to open, the electrolysis tank 37 is not energized at this switching timing, and an attempt is made to energize the electrolysis tank 37 while the power is stable. It is a thing.

After that, at a time t16 when a predetermined time T3 (for example, 1.9 seconds) has elapsed from the time t14 when the second electromagnetic valve 28 is opened, the controller 40 stops the energization of the electrolysis tank 37 and the electrolysis tank 37 The production of electrolyzed water at 37 is terminated. At this time, since the second electromagnetic valve 28 is still open, the spray water discharge from the second water discharge portion 13 is continued. Then, at a time t17 after the time t16, specifically, at a time t17 when a predetermined time T2 (for example, 3.5 seconds) has elapsed from the time t14 when the second electromagnetic valve 28 was opened, the controller 40 causes the LED 15 to operate. Is turned off to end the irradiation of the light from the LED 15, and the second solenoid valve 28 is closed by stopping the energization of the second solenoid valve 28, thereby spraying from the second water discharger 13. The water discharge is ended, that is, the after water discharge is ended.

Here, it is advisable to extend the life (years of durability) of the electrolytic cell 37 and perform the above-described control relating to after-water discharge.

In one example, the controller 40 does not perform after-water discharge each time the hand-wash water is discharged, but performs after-water discharge every time the hand-wash water discharge is performed a predetermined number of times. Specifically, the controller 40 counts the number of times water is discharged for hand washing, does not perform after-water discharge while the number of times of counting has reached a predetermined number, and when the number of times of counting reaches a predetermined number of times. After-water discharge is performed, the number of times counted at this time is reset, and the number of times of hand-wash water discharge is counted again. In this case, the controller 40 applies electrolyzed water when performing after-water discharge.

In another example, the controller 40 performs after-water discharge every time the hand-wash water is discharged, but performs after-water discharge to which electrolytic water is applied and after-water discharge to which electrolytic water is not applied (that is, after-water discharge to which normal water is applied). Switch appropriately and perform. In this case, the controller 40 applies electrolyzed water every time after-water discharge is performed a predetermined number of times. Specifically, the controller 40 counts the number of times the after-water discharge is performed, and while the counted number does not reach the predetermined number of times, by not energizing the electrolytic cell 37, the after-water discharge to which the normal water is applied is performed. When the counted number of times reaches a predetermined number of times, the electrolytic cell 37 is energized to perform after-water discharge applying electrolyzed water, and the number of times counted at this time is reset to perform the after-water discharge. Will be counted again.

In still another example, the controller 40 performs after-water discharge every time the hand-wash water is discharged, but performs after-water discharge by changing the energization time of the electrolytic cell 37. That is, the controller 40 changes the concentration of electrolyzed water to be applied when performing after-water discharge. Specifically, the controller 40 learns the usage frequency of the automatic faucet device 1 and adjusts the energization time of the electrolytic cell 37 based on the usage frequency. Specifically, the controller 40 shortens the energization time of the electrolytic cell 37 as the learned usage frequency increases, in other words, the energization time of the electrolytic cell 37 increases as the learned usage frequency decreases.

In addition, although the control regarding after-water discharge performed in consideration of the lifetime (durability years) of the electrolytic bath 37 has been described above, the control is not limited to such control, and the bowl 3 of the hand washing device 5 is cleaned. The after-water discharge control may be performed by giving priority to the maintenance. In this case, since the bowl 3 of the hand washing device 5 is soiled after the user has washed his/her hand, the controller 40 preferably performs after-water discharge by applying electrolytic water every time the water for hand-wash is discharged.

Next, referring to FIG. 8, electrolyzed water is generated only during an initial period (a period indicated by T3 in FIG. 7) in a period during which after-water discharge is performed (a period indicated by T2 in FIG. 7). The reason why normal water is flown without generating electrolyzed water in the later period will be described. FIG. 8 schematically shows the second flow passage 18 and the second water discharger 13 on the upstream side of the electrolytic cell 37, and shows the state of the water in the second flow passage 18 during the after-water discharge period. Are shown in chronological order from left to right. In FIG. 8, the normal water and the electrolyzed water in the second flow path 18 are shown in different modes.

First, at the start of after-water discharge, the controller 40 switches the second electromagnetic valve 28 from closed to open to start energization of the electrolytic cell 37. At this time, the inside of the second flow path 18 is normally. Since it is filled with water, normal water is discharged from the second water discharge part 13 (see FIG. 8A). After this, the electrolyzed water generated in the electrolyzer 37 flows downstream in the second flow path 18 (see FIG. 8B), and when the electrolyzed water reaches the downstream end of the second flow path 18. That is, when reaching the second water discharger 13 (at this time, the inside of the second flow path 18 is filled with the electrolytic water), the electrolytic water starts to be discharged from the second water discharger 13 (FIG. 8). (See (C)). After that, the controller 40 stops the energization of the electrolysis tank 37 and stops the generation of electrolyzed water in the electrolysis tank 37 while keeping the second electromagnetic valve 28 open. Then, the normal water is supplied to the second flow path 18 and the electrolyzed water in the second flow path 18 is pushed out, whereby the electrolyzed water is discharged from the second water discharger 13 and the second flow is generated. The electrolyzed water in the passage 18 is gradually replaced with normal water (see FIG. 8D). Then, finally, the electrolyzed water in the second flow path 18 is almost lost, and the second flow path 18 is filled with normal water (see FIG. 8E). At this time, the controller 40 switches the second electromagnetic valve 28 from open to closed, and ends the spray water discharge from the second water discharge part 13, that is, the after-water discharge.

In this way, in the present embodiment, the inside of the second flow path 18 is filled with normal water when the after-water discharge using the electrolyzed water is completed. By doing so, corrosion (deterioration) of the second flow path 18 and the like due to the retention of the electrolyzed water in the second flow path 18 is suppressed. In this case, the controller 40 stops supplying electricity to the electrolyzer 37 and then supplies the same amount of normal water as the volume of the second flow path 18 (the volume including the second water discharger 13 may be used) or By supplying the normal water to the second flow path 18 by keeping the second electromagnetic valve 28 open for a time required for a larger amount of the normal water to flow through the second flow path 18, At the end of the after-water discharge, the state in which the second flow path 18 is normally filled with water is created.

In one example, when the volume of the second flow path 18 is 8 cc and the flow rate in the second flow path 18 is 5 cc per second, it is necessary to fill the second flow path 18 with normal water. Since it takes 1.6 seconds, the controller 40 keeps the second electromagnetic valve 28 open for 1.6 seconds after stopping the energization of the electrolytic cell 37 to supply normal water to the second flow path 18. Supply. In this example, when the after-water discharge is to be performed for 3.5 seconds (corresponding to the predetermined time T2 shown in FIG. 7), the controller 40 sets the first 1.9 seconds (the predetermined time shown in FIG. 7). (Corresponding to T3), the electrolysis tank 37 is energized with the second solenoid valve 28 opened, and the second solenoid valve 28 is operated with the energization of the electrolysis vessel 37 stopped for the subsequent 1.6 seconds. Keep it open. In such a case, normal water is discharged for the first 1.6 seconds, and electrolyzed water is discharged for the subsequent 1.9 seconds.

In the above-described example, 1.6 seconds is the minimum time required to fill the second flow path 18 with normal water after stopping the energization of the electrolytic cell 37. It is not limited to keep the second solenoid valve 28 open and supply the normal water to the second flow path 18 for a second, and the second solenoid valve 28 is opened for a time longer than 1.6 seconds. Alternatively, normal water may be supplied to the second flow path 18. Doing so corresponds to supplying normal water in an amount larger than the volume of the second flow path 18 to the second flow path 18. In such a case, the normal water is discharged for a while after the electrolyzed water is discharged, and the electrolyzed water discharged to the bowl 3 or the like of the handwasher 5 can be flushed by the normal water, so that the bowl 3 or a plate or the like can be discharged. It is possible to suppress the influence of electrolyzed water.

In the example described above, in the after-water discharge, after the electrolytic water is discharged from the second water discharge part 13, the electricity supply to the electrolytic cell 37 is stopped and the electrolytic water is supplied to the second flow path 18. Although the water was stopped and the normal water was supplied to the second flow path 18, in another example, after discharging the electrolytic water from the second water discharger 13, without stopping the energization of the electrolytic bath 37, It is also possible to reduce the energization power (which means current or voltage) of the electrolytic cell 37 and supply not the normal water but the electrolytic water having a low concentration to the second flow path 18.
In this case, the controller 40 first applies the first energization power to the electrolysis tank 37 to generate electrolysis water of the first concentration in the electrolysis tank 37, and to generate the electrolysis water of the first concentration. , Water is discharged from the second water discharger 13 through the second flow path 18, and then, second electric power that is lower than the first electric power is applied to the electrolytic tank 37. A second concentration of electrolyzed water lower than the first concentration is generated, and the second concentration of electrolyzed water is supplied to the second flow path 18. For example, as the first concentration of electrolyzed water, the concentration of electrolyzed water having a sufficient sterilizing function is applied, and as the second concentration of electrolyzed water, the influence on the second flow path 18 is considerably small. A concentration of electrolyzed water (preferably, a concentration of electrolyzed water capable of sufficiently diluting the first concentration of electrolyzed water filled in the second flow path 18) is applied. Note that when the second energization power applied to the electrolysis tank 37 is set to 0, the energization to the electrolysis tank 37 is stopped and the second concentration becomes 0. Will be supplied to the channel 18.
According to such another example as well, after the electrolyzed water having the relatively high first concentration is discharged, the electrolyzed water having the relatively low second concentration is supplied to the second flow path 18, so that the second concentration is increased. With the electrolyzed water, the concentration of electrolyzed water in the second flow path 18 can be reduced, and corrosion (deterioration) of the second flow path 18 and the like due to electrolyzed water can be suppressed.

Next, with reference to FIGS. 9 to 11, another control example that is performed based on the above-described basic control (see FIG. 7) in the first embodiment of the present invention will be described.

FIG. 9 is a time chart showing a first control example according to the first embodiment of the present invention. FIG. 9 shows, in order from the top, the sensor signal supplied from the sensor 14 to the controller 40, the drive signal supplied from the controller 40 to the second electromagnetic valve 28, and the drive signal supplied from the controller 40 to the first electromagnetic valve 25. Shows the signal.
Here, description of the same control as the basic control described above will be appropriately omitted. Specifically, the control from the time t21 to the time t22 and the control after the time t24 are the same as the basic control, so the description thereof will be omitted and only the control from the time t22 to the time t24 will be described.

In the basic control described above, the after-water discharge is executed when the predetermined time T1 has elapsed after the hand-wash water discharge was executed, but in the first control example, the predetermined time T1 is executed after the hand-wash water discharge is executed. It relates to the control performed when the sensor 14 switches from the non-detection state to the detection state before the time elapses. Specifically, in the first control example, the controller 14 switches from the non-detection state to the detection state at a time t23 before the predetermined time T1 elapses after the time t22 at which the water for hand washing is finished, so that the controller 40 energizes the 1st electromagnetic valve 25, opens the 1st electromagnetic valve 25, and makes foam water discharge from the 1st water discharge part 12. In this case, the controller 40 maintains the first electromagnetic valve 25 in the open state from the time t23 when the detection state of the sensor 14 continues to the time t24, and causes the first water discharger 12 to perform the foam water discharge. That is, sprinkle water for hand washing.

As described above, in the first control example, when the sensor 14 is in the detection state within a period after performing the water discharge for hand washing and before performing the after-water discharge, the spray water discharge by the second water discharge unit 13 is not performed. , The first water spouting part 12 performs foam water spouting. By doing so, when the sensor 14 temporarily switches from the non-detection state to the detection state after the spouting water for hand washing (for example, the user temporarily moves his/her hand out of the detection range of the sensor 14 during hand washing). In that case, the water for hand washing is restarted without starting the after-water discharge. That is, the user can restart the hand washing without waiting for the end of after-water discharge.

Next, FIG. 10 is a time chart showing a second control example according to the first embodiment of the present invention. In FIG. 10, in order from the top, the sensor signal supplied from the sensor 14 to the controller 40, the drive signal supplied from the controller 40 to the second electromagnetic valve 28, and the drive signal supplied from the controller 40 to the first electromagnetic valve 25. Shows the signal.
Here, description of the same control as the basic control described above will be appropriately omitted. Specifically, the control from the time t31 to the time t33 and the control after the time t35 are the same as the basic control, so the description thereof will be omitted and only the control from the time t34 to the time t35 will be described.

The second control example relates to control performed when the sensor 14 switches from the non-detection state to the detection state during execution of after-water discharge. Specifically, in the second control example, at time t34 during execution of after-water discharge, the sensor 40 switches from the non-detection state to the detection state, so that the controller 40 energizes the second solenoid valve 28. Stop and close the second electromagnetic valve 28 (if the electrolysis tank 37 is energized, the energization of the electrolysis tank 37 is also stopped), and while stopping the spray water discharge from the second water discharge unit 13, The first electromagnetic valve 25 is energized to open the first electromagnetic valve 25, and foam water is discharged from the first water discharger 12. That is, the controller 40 ends the after-water discharge and starts the hand-wash water discharge. In this case, the controller 40 maintains the first electromagnetic valve 25 in the open state from the time t34 to the time t35 when the detection state of the sensor 14 continues, and causes the first water spouting portion 12 to perform foam water discharge. .. Then, the controller 40 energizes the second solenoid valve 28 at the time t36 when the non-detection state of the sensor 14 continues for the predetermined time T1 after the time t35 when the hand-washing water discharge is finished, and the second solenoid valve 28 is energized. The valve 28 is opened to perform spray water discharge by the second water discharge unit 13, that is, restart after-water discharge.

As described above, in the second control example, when the sensor 14 is in the detection state during execution of after-water discharge, the spray water discharge by the second water discharge unit 13 is stopped and the foam water discharge by the first water discharge unit 12 is stopped. Do, that is, stop after-water discharge and perform hand-wash water discharge. By doing so, the user can wash the hands without waiting for the end of after-water discharge. Also, if electrolyzed water gets into the user's hands, it may cause skin roughness depending on the concentration of the electrolyzed water, or the odor (chlorine odor, etc.) peculiar to electrolyzed water may remain. By stopping the after-water discharge when the sensor 14 is in the detection state during the execution of (1), it is possible to prevent such a problem that may occur when the electrolyzed water falls on the user's hand.

Next, FIG. 11 is a time chart showing a third control example according to the first embodiment of the present invention. FIG. 11 shows the drive signal supplied from the controller 40 to the second solenoid valve 28 at the top and the drive signal supplied from the controller 40 to the electrolytic cell 37 at the bottom. Here, description of the same control as the basic control described above will be appropriately omitted.

In the above-mentioned basic control, it has been described that the energization of the electrolysis tank 37 is started after the energization of the second solenoid valve 28 is started without simultaneously energizing the second solenoid valve 28 and the electrolysis tank 37. In the third control example, in addition to this control, the controller 40 does not stop the energization of the second electromagnetic valve 28 and the energization of the electrolytic cell 37 at the same time, and after stopping the energization of the electrolytic cell 37. The energization of the second solenoid valve 28 is stopped. Specifically, the controller 40 energizes the second electromagnetic valve 28 at time t41, energizes the electrolysis tank 37 at time t42 immediately thereafter, then stops energization of the electrolysis tank 37 at time t43, and immediately thereafter. At time t44, the energization of the second solenoid valve 28 is stopped. For example, the controller 40 stops the energization of the electrolytic bath 37 and the second electromagnetic valve 28 in such a procedure when the sensor 14 is in the detection state during the execution of the after-water discharge generating electrolytic water. ..

In this way, the energization of the second solenoid valve 28 is stopped after the energization of the electrolysis bath 37 without stopping the energization of the second solenoid valve 28 and the energization of the electrolysis bath 37 at the same time. Since a large amount of electric power is consumed at the timing of switching the second electromagnetic valve 28 from open to closed, it is possible to stop the energization of the electrolytic cell 37 at the timing of this switching, and The second solenoid valve 28 is operated. Note that a large amount of electric power is consumed during the period in which both the second electromagnetic valve 28 and the electrolytic cell 37 are energized (the period from time t42 to time t43), so the second electromagnetic valve 28 is supplied with power. The electric power to be applied may be appropriately thinned, and specifically, the energization of the second solenoid valve 28 may be temporarily stopped. After the second solenoid valve 28 is once opened, even if the energization of the second solenoid valve 28 is temporarily stopped, the second solenoid valve 28 is hardly closed and the second solenoid valve 28 is not closed. This is because the valve open state of 28 can be maintained.

Next, a control flow performed by the controller 40 in the first embodiment of the present invention will be described with reference to FIGS. 12 and 13. FIG. 12 is a flow chart showing a control flow relating to water spouting for hand washing according to the first embodiment of the present invention, and FIG. 13 is for after-water spouting according to the first embodiment of the present invention performed after the flow chart shown in FIG. It is a flowchart which shows the control flow which concerns. Note that the control flows shown in FIGS. 12 and 13 apply the first to third control examples (see FIGS. 9 to 11) to the basic control (see FIG. 7).

First, the control flow relating to the water spout for hand washing according to the first embodiment of the present invention shown in FIG. 12 will be described.

First, in step S11, the controller 40 determines whether the sensor signal from the sensor 14 has switched from off to on, that is, whether the sensor 14 has switched from a non-detection state to a detection state. As a result, when the sensor signal is not switched from off to on (step S11: No), the determination of step S11 is performed again. That is, the controller 40 repeats the determination of step S11 until the sensor signal switches from off to on.

On the other hand, when the sensor signal is switched from OFF to ON (step S11: Yes), the process proceeds to step S12, the controller 40 energizes the first solenoid valve 25 to open the first solenoid valve 25, Ordinary water is spouted from the first water spouting section 12, that is, hand spouting is performed.

Next, in step S13, the controller 40 determines whether or not the sensor signal from the sensor 14 has switched from on to off, that is, whether or not the sensor 14 has switched from a detection state to a non-detection state. As a result, when the sensor signal is not switched from on to off (step S13: No), the determination in step S13 is performed again. That is, the controller 40 repeats the determination of step S13 until the sensor signal switches from on to off. In this case, the controller 40 continues the energization of the first electromagnetic valve 25 and maintains the open state of the first electromagnetic valve 25, thereby continuously performing the water discharge for hand washing.

On the other hand, when the sensor signal is switched from on to off (step S13: Yes), the process proceeds to step S14, where the controller 40 stops energizing the first solenoid valve 25 and closes the first solenoid valve 25. The valve is closed to end the foam water discharge from the first water discharge part 12, that is, the hand wash water discharge is ended. Then, the process proceeds to step S20 shown in FIG.

Next, a control flow relating to after-water discharge according to the first embodiment of the present invention shown in FIG. 13 will be described.

First, in step S20, the controller 40 determines whether the sensor signal from the sensor 14 is off, that is, whether the sensor 14 is in the non-detection state. As a result, when the sensor signal is not off (step S20: No), that is, when the sensor signal is switched from off to on, the process returns to step S12 shown in FIG. In this case, as described above, the controller 40 energizes the first electromagnetic valve 25 to open the first electromagnetic valve 25, and causes the first water discharger 12 to normally spout water for foam washing. Repeat the water discharge.

On the other hand, when the sensor signal is off (step S20: Yes), the controller 40 proceeds to step S21, and the controller 40 has passed 3 seconds (corresponding to the predetermined time T1 shown in FIG. 7) after ending the hand washing water discharge. It is determined whether or not. As a result, when 3 seconds have not elapsed since the end of the hand washing water discharge (step S21: No), the process returns to step S20, and the determinations in steps S20 and S21 are performed again. In this case, the controller 40 waits for 3 seconds while determining whether or not the sensor signal is off.

On the other hand, when 3 seconds have passed since the end of the hand washing water discharge (step S21: Yes), the process proceeds to step S22, and the controller 40 turns on the LED 15. Immediately after that, in step S23, the controller 40 energizes the second electromagnetic valve 28 to open the second electromagnetic valve 28, and immediately after that, in step S24, the controller 40 energizes the electrolytic cell 37. Then, electrolyzed water is generated in the electrolytic bath 37. By doing so, the controller 40 sprays electrolytic water from the second water discharger 13, that is, performs after-water discharge.
Strictly speaking, the controller 40 passes 3 seconds after ending the hand-washing water discharge so that the second electromagnetic valve 28 opens at the time point 3 seconds after ending the hand-washing water discharge. At a previous time point, that is, when a predetermined time of less than 3 seconds has passed after the end of the hand washing water discharge, the LED 15 is turned on.

Next, in step S25, the controller 40 determines whether the sensor signal from the sensor 14 is off, that is, whether the sensor 14 is in the non-detection state. As a result, when the sensor signal is not off (step S25: No), that is, when the sensor signal is switched from off to on, the process proceeds to step S26. In this case, in step S26, the controller 40 stops the energization of the electrolytic bath 37 and ends the generation of electrolyzed water in the electrolytic bath 37. Immediately after that, in step S27, the controller 40 turns off the LED 15, stops energizing the second electromagnetic valve 28, and closes the second electromagnetic valve 28. By doing so, the controller 40 ends the spray water discharge from the second water discharge unit 13, that is, the after-water discharge. After that, the process returns to step S12 shown in FIG. 12, and the controller 40 energizes the first solenoid valve 25 to open the first solenoid valve 25 as described above, and Use normal water as a foam spout and repeat the hand spout.

On the other hand, when the sensor signal is off (step S25: Yes), the process proceeds to step S28, and the controller 40 starts 1.9 seconds after the after-water discharge (corresponding to the predetermined time T3 shown in FIG. 7). It is determined whether or not it has passed. As a result, when 1.9 seconds have not elapsed since the start of after-water discharge (step S28: No), the process returns to step S25 and the determinations of steps S25 and S28 are performed again. In this case, the controller 40 waits for 1.9 seconds to elapse while determining whether or not the sensor signal is off.

On the other hand, when 1.9 seconds have passed since the after-water discharge was started (step S28: Yes), the process proceeds to step S29, where the controller 40 stops energizing the electrolytic bath 37 and electrolyzes the electrolytic bath 37. The production of water is completed.

Next, in step S30, the controller 40 determines whether the sensor signal from the sensor 14 is off, that is, whether the sensor 14 is in the non-detection state. As a result, when the sensor signal is not off (step S30: No), that is, when the sensor signal is switched from off to on, the process proceeds to step S27. In this case, in step S27, the controller 40 turns off the LED 15, stops energizing the second electromagnetic valve 28, and closes the second electromagnetic valve 28. By doing so, the controller 40 ends the spray water discharge from the second water discharge unit 13, that is, the after-water discharge. After that, the process returns to step S12 shown in FIG. 12, and the controller 40 energizes the first solenoid valve 25 to open the first solenoid valve 25 as described above, and Use normal water as a foam spout and repeat the hand spout.

On the other hand, when the sensor signal is off (step S30: Yes), the controller 40 proceeds to step S31, and 3.5 seconds after starting the after-water discharge (corresponding to the predetermined time T2 shown in FIG. 7). It is determined whether or not it has passed. As a result, when 3.5 seconds have not elapsed after the after-water discharge is started (step S31: No), the process returns to step S30, and the determinations in steps S30 and S31 are performed again. In this case, the controller 40 waits for 3.5 seconds while determining whether or not the sensor signal is off.

On the other hand, when 3.5 seconds have passed since the after-water discharge was started (step S31: Yes), the process proceeds to step S32, where the controller 40 turns off the LED 15 and energizes the second solenoid valve 28. After stopping, the second solenoid valve 28 is closed. By doing so, the controller 40 ends the spray water discharge from the second water discharge unit 13, that is, the after-water discharge.

(Operation and effect of the first embodiment)
Next, operation effects of the automatic faucet device according to the first embodiment of the present invention will be described.

According to the first embodiment, the water for hand washing is discharged when the sensor 14 is in the detection state, and when the sensor 14 is in the non-detection state, the water discharge for hand washing is ended and the after-water discharge is performed thereafter (see FIG. 7). If there is a possibility that the dirt flowing out by the hand washing with the water spout for hand washing may be dried and adhered to the bowl 3 of the hand washing device 5 or the like, it is possible to appropriately perform the after-water spouting, which is wasteful. While suppressing water discharge, it is possible to prevent such dirt from adhering to the bowl 3 or the like of the hand washing device 5 by drying. Therefore, the bowl 3 and the like of the hand washing device 5 can be kept clean. In particular, according to the first embodiment, since the after-water discharge is performed using the electrolyzed water, the bowl 3 and the like of the handwasher 5 can be effectively kept clean.

Further, the water (dirty water) flowing out by the hand washing using the hand washing spout tends to fall in a range wider than the spouting range of the hand washing spout, but according to the first embodiment, the foam spouting used in the hand washing spout. Since after-water discharge is performed using spray water discharge having a wider water discharge angle than the water discharge port, it is possible to discharge water in a wide range with a small flow rate, while effectively suppressing wasteful water discharge, while maintaining the handwasher 5 of the handwasher 5. The bowl 3 and the like can be effectively kept clean. In this case, it is difficult for the user to predict the spraying/spraying range R11 of the sprayed water, but according to the first embodiment, the LED 15 irradiates a range R12 that is substantially the same as the sprayed/spraying range R11 (FIG. 4). It is possible to appropriately notify the user of the water discharge range R11 of the spray water, and it is possible to prevent the user from landing on an undesired location. In particular, according to the first embodiment, before the spray spouting is started, the user is informed in advance of the spraying spouting water discharge range R11 by the light from the LED 15 (see FIG. 7), so that the user does not want to do this. It is possible to effectively prevent the water from landing on.

Further, according to the first embodiment, after the water spout for hand washing is finished, after the water spouting is performed when the non-detection state of the sensor 14 continues for a predetermined time (see FIG. 7), the end of the water spout for hand washing and thereafter The user can be notified of the start of after-water discharge. If electrolyzed water generated by after-water discharge comes into contact with the user's hands, the skin may become rough depending on the concentration of electrolyzed water, or the odor (chlorine odor, etc.) peculiar to electrolyzed water may remain. By thus notifying the user of the start of the after-water discharge, it is possible to appropriately prevent a problem that may occur due to the electrolytic water falling on the user's hand.

Further, according to the first embodiment, when the sensor 14 is in the detection state before the after-water discharge after the water discharge for hand washing, the foam water discharge is performed without performing the spray water discharge (see FIG. 9 ). When the sensor switches from the temporary non-detection state to the detection state after spouting water for hand washing (for example, when the user temporarily moves the hand out of the detection range of the sensor 14 during hand washing), after-sales It is possible to properly restart the water spout for hand washing without starting the water spout. That is, the user can restart the hand washing without waiting for the end of the after-water discharge.

Further, according to the first embodiment, when the sensor 14 is in the detection state during after-water discharge, the spray-water discharge is stopped and the foam water discharge is performed, that is, the after-water discharge is stopped and the hand-wash water discharge is performed. (See FIG. 10), the user can wash the hands without waiting for the end of the after-water discharge, and it is possible to prevent the above-mentioned problems that may occur due to the electrolytic water falling on the user's hands. ..

Further, according to the first embodiment, when the after-water discharge is started, the energization of the electrolytic bath 37 is started after the energization of the second electromagnetic valve 28 is started, and the electric power of the electrolytic bath 37 is stable when the electric power is stable. When the energization is started and the after-water discharge is finished, the energization of the second electromagnetic valve 28 is stopped after the energization of the electrolytic cell 37 is stopped, and the second electromagnetic valve 28 is turned on in the state where the electric power is stable. Since the operation is performed from the open state to the closed state (see FIG. 11), it is possible to appropriately deal with a power source having a small capacity, and it is possible to downsize the device.

Further, according to the first embodiment, after-water spouting is not performed every time water-spraying for hand-washing is performed, after-water spouting is performed every predetermined number of water-washing spouts for hand-washing, and the frequency of use of the automatic faucet device 1 is learned. Then, by adjusting the energization time of the electrolytic cell 37 based on the frequency of use, the load applied to the electrolytic cell 37 can be reduced, and the life (years of durability) of the electrolytic cell 37 can be extended.

Furthermore, according to the first embodiment, in the after-water discharge, after the electrolytic water is discharged from the second water discharge part 13, the energization of the electrolytic cell 37 is stopped, and the electrolytic water to the second flow path 18 is stopped. Since the supply is stopped and the normal water is supplied to the second flow path 18 (see FIGS. 7 and 8 ), the supplied normal water discharges the electrolyzed water in the second flow path 18 to generate the normal water. By replacing, the concentration of the electrolyzed water in the second flow path 18 can be reduced (when a sufficient amount of normal water is supplied, almost all of the electrolyzed water in the second flow path 18 is discharged. The inside of the second flow path 18 can be normally filled with water). As a result, it is possible to suppress corrosion (deterioration) of the second flow path 18 and the like due to the retention of electrolyzed water in the second flow path 18. Here, a method of adjusting the concentration of electrolyzed water in order to suppress the corrosion of the second flow path 18 and the like is conceivable, but in that case, it is necessary to adjust the electrolyzed water to a concentration such that corrosion is suppressed However, according to the first embodiment, since normal water is supplied to the second flow path 18 as described above, electrolytic water of various concentrations can be supplied without considering the corrosion of the second flow path 18 and the like. Can be applied.

On the other hand, according to the first embodiment, the first spout 12a of the first spout 12, the second spout 13a of the second spout 13, and the sensor 14 are provided at the tip. In the automatic faucet device 1, since the first spout 12a is arranged between the sensor 14 and the second spout 13a (see FIG. 2B), the sensor 14 and the second spout 13a. 13a can be separated from each other, and erroneous water discharge caused by the sensor 14 detecting water sprayed and discharged from the second water discharge port 13a can be suppressed. Particularly, according to the first embodiment, since the LED 15 is further arranged between the first water outlet 12a and the second water outlet 13a (see FIG. 2B), the sensor 14 and the second The water discharge port 13a can be further separated, and the above-mentioned erroneous water discharge can be effectively suppressed. In addition, since the LED 15 is arranged in the vicinity of the second water discharge port 13a, it is possible to appropriately irradiate the water discharge range R11 of the second water discharge unit 13 with the light from the LED 15.

Further, according to the first embodiment, since the sensor 14 is arranged on the front side of the second water discharge port 13a (see FIG. 2(B)), the sensor 14 is arranged on the rear side of the second water discharge port 13a. Compared to the case where the sensor 14 is provided, the user does not have to forcibly extend the hand to the rear side in order to make the sensor 14 detect the hand. In addition, since the second water discharge port 13a is arranged on the rear side of the sensor 14 (see FIG. 2B), when the second water discharge port 13a is arranged on the front side of the sensor 14. Compared with the above, the water sprayed and spouted from the second spout 13a is less likely to splash on a portion of the user's arm or body that should not be wetted.

In addition, according to the first embodiment, the sensor 14 is arranged so that the detection direction A23 of the sensor 14 faces away from the water discharge direction A22 of the second water discharger 13. Therefore, in other words, the sensor The sensor 14 is arranged so that the line L13 along the detection direction A23 of 14 does not intersect with the line L12 extending in the vertical direction from the center of the second water outlet 13a of the second water discharger 13 on the front side. (See FIG. 5), the sensor 14 intersects with the water discharge range R11 of the second water discharger 13 at a part where the detection accuracy is considerably low in the pointing range R13 (that is, at a part far from the sensor 14 in the pointing range R13). Therefore, it is possible to more effectively suppress erroneous water discharge caused by the sensor 14 detecting the water sprayed and discharged from the second water discharge port 13a.

Further, according to the first embodiment, the first water spouting portion 12 and the water spouting direction A21 of the first water spouting portion 12 and the water spouting direction A22 of the second water spouting portion 13 are oriented so as to be away from each other. Since each of the second water discharge parts 13 is provided, in other words, a line L11 extending in the vertical direction from the center of the first water discharge port 12a and a line extending in the vertical direction from the center of the second water discharge port 13a. Since each of the first water discharger 12 and the second water discharger 13 is arranged so as not to intersect L12 on the front side (see FIG. 5), the second water discharger 13 faces downward. Thus, the spray water can be sprayed, and it is possible to appropriately prevent the water spray-sprayed from the second water discharger 13 from splashing on the user.

Further, according to the first embodiment, since the second water outlet 13a is disposed on the rear side of the first water outlet 12a (see FIG. 2(B)), the first water outlet 12a It is possible to properly prevent the water from dripping on the second spout 13a. In this case, according to the first embodiment, by applying the orientation of the second water discharger 13 in consideration of the position of the first water discharge outlet 12a, the water sprayed and discharged from the second water discharge outlet 13a is applied. It is possible to appropriately prevent the water from getting on the first spout 12a.

(Second embodiment)
Next, the control performed by the controller 40 in the second embodiment of the present invention will be described. In the above-described first embodiment, in the spout for hand washing, only the foam spouting from the first spouting portion 12 is performed, but in the second embodiment, the spouting from the first spouting portion 12 is performed in the spouting water for hand washing. Not only water spouting but also spray water spouting from the second water spouting portion 13 is performed. Specifically, in the second embodiment, in the water spout for hand washing, the controller 40 first performs spray water spouting from the second water spouting unit 13 for a predetermined time, and then performs foam water spouting from the first water spouting unit 12. To do.

In addition, below, about the control similar to 1st Embodiment mentioned above, those description is abbreviate|omitted suitably and only the control different from 1st Embodiment is demonstrated. That is, the control not particularly described here is the same as that of the first embodiment.

FIG. 14 is a time chart showing basic control according to the second embodiment of the present invention. FIG. 14 shows, in order from the top, the sensor signal supplied from the sensor 14 to the controller 40, the drive signal supplied from the controller 40 to the second solenoid valve 28, and the drive signal supplied from the controller 40 to the first solenoid valve 25. The signal, the drive signal supplied from the controller 40 to the electrolytic bath 37, and the drive signal supplied from the controller 40 to the LED 15 are shown.
Here, the control after time t54 is the same as the basic control according to the first embodiment, so the description thereof will be omitted and only the control from time t51 to time t54 will be described.

First, at time t51, the sensor signal switches from OFF to ON, that is, the sensor 14 switches from the non-detection state to the detection state. At this time, the controller 40 energizes the second electromagnetic valve 28 to open the second electromagnetic valve 28 and cause the second water discharger 13 to spray water. In this case, the controller 40 sprays normal water from the second water discharger 13 without turning on the LED 15 and without energizing the electrolytic bath 37, that is, without generating electrolytic water in the electrolytic bath 37. Let The controller 40 applies such spray water discharge as water discharge to be performed initially in water discharge for hand washing. Then, the controller 40 stops energizing the second solenoid valve 28 at time t52 when a predetermined time T5 (for example, 3 seconds) has elapsed from the time t51 when the spray water discharge from the second water discharge part 13 was started. By closing the second electromagnetic valve 28, the spray water discharge from the second water discharger 13 is completed.

Then, at a time t53 when a certain time (for example, 0.5 seconds) has elapsed from the time t52 when the spray water discharge from the second water discharger 13 is finished, the controller 40 energizes the first solenoid valve 25 to make the first time. The electromagnetic valve 25 of No. 1 is opened, and the normal water is spouted from the first water spouting section 12 in the form of foam. The controller 40 applies such foam spouting as spouting performed after spray spouting in hand-washing spouting. After that, at time t54, the sensor signal switches from on to off, that is, the sensor 14 switches from the detection state to the non-detection state. At this time, the controller 40 stops energizing the first electromagnetic valve 25 and closes the first electromagnetic valve 25, and ends the foam water discharge from the first water discharge unit 12. By doing this, the water for hand washing is finished. After that, the controller 40 performs after-water discharge in the same procedure as in the first embodiment.

It should be noted that it is preferable that the predetermined time T5 for spraying water in the water for hand washing can be adjusted. Specifically, an adjusting part such as a switch is provided in the automatic faucet device 1, and the environment in which the automatic faucet device 1 is used (characteristics of the user of the automatic faucet device 1, installation location of the automatic faucet device 1, etc.) Accordingly, it is preferable that the administrator or the like can adjust the predetermined time T5 by using the adjusting unit.

Next, with reference to FIG. 15, a control flow performed by the controller 40 in the second embodiment of the present invention will be described. FIG. 15 is a flowchart showing a control flow relating to spouting water for hand washing according to the second embodiment of the present invention.
Even after the control flow related to the water discharge for hand washing according to the second embodiment is completed, the control flow related to the after-water discharge shown in FIG. 13 described above is similarly executed.

First, in step S41, the controller 40 determines whether the sensor signal from the sensor 14 has switched from off to on, that is, whether the sensor 14 has switched from a non-detection state to a detection state. As a result, when the sensor signal is not switched from off to on (step S41: No), the determination in step S41 is performed again. That is, the controller 40 repeats the determination of step S41 until the sensor signal switches from off to on.

On the other hand, when the sensor signal is switched from OFF to ON (step S41: Yes), the process proceeds to step S42, the controller 40 energizes the second solenoid valve 28 to open the second solenoid valve 28, Spray water is sprayed from the second water discharger 13. By doing this, spouting water for hand washing is started.

Next, proceeding to step S43, the controller 40 determines whether or not 3 seconds (corresponding to the predetermined time T5 shown in FIG. 14) has elapsed since the start of spray water discharge as water discharge for hand washing. As a result, if 3 seconds have not elapsed since the start of spray water discharge (step S43: Yes), the process proceeds to step S44, and the controller 40 determines whether or not the sensor signal from the sensor 14 has been switched from on to off. That is, it is determined whether or not the sensor 14 is switched from the detection state to the non-detection state. As a result, when the sensor signal is switched from on to off (step S44: Yes), the process proceeds to step S45, where the controller 40 stops energizing the second solenoid valve 28 and closes the second solenoid valve 28. The valve is closed, and the spray water discharge from the second water discharge part 13 is completed. As a result, the water for hand-washing is completed. Then, the process proceeds to step S20 shown in FIG.

On the other hand, when the sensor signal is not switched from on to off (step S44: No), the process returns to step S43, and the determinations of steps S43 and S44 are performed again. That is, the controller 40 waits for 3 seconds while determining whether or not the sensor signal is switched from on to off. In this case, the controller 40 continues to energize the second electromagnetic valve 28 and maintains the open state of the second electromagnetic valve 28, thereby continuing the spray water discharge from the second water discharge unit 13. To do.

On the other hand, when 3 seconds have elapsed since the start of spray water discharge (step S43: No), the process proceeds to step S46, and the controller 40 stops the energization of the second solenoid valve 28 to stop the second solenoid valve 28. Is closed, and the spray water discharge from the second water discharge part 13 is completed.

Next, in step S47, the controller 40 energizes the first electromagnetic valve 25 to open the first electromagnetic valve 25, and starts foam water discharge from the first water discharge unit 12. In this case, the controller 40 starts such foam water discharge after a lapse of a predetermined time (for example, 0.5 seconds) from the end of spray water discharge.

Next, in step S48, the controller 40 determines whether or not the sensor signal from the sensor 14 has switched from on to off, that is, whether or not the sensor 14 has switched from a detection state to a non-detection state. As a result, when the sensor signal is not switched from on to off (step S48: No), the determination of step S48 is performed again. That is, the controller 40 repeats the determination of step S48 until the sensor signal switches from on to off. In this case, the controller 40 continues energizing the first solenoid valve 25 and maintains the open state of the first solenoid valve 25 to continue the foam water discharge from the first water discharge part 12. To do.

On the other hand, when the sensor signal is switched from on to off (step S48: Yes), the process proceeds to step S49, where the controller 40 stops energizing the first solenoid valve 25 and closes the first solenoid valve 25. The valve is closed, and the foam water discharge from the first water discharge unit 12 is completed. As a result, the water for hand-washing is completed. Then, the process proceeds to step S20 shown in FIG.

In the case of executing the control flow according to the second embodiment, if the determination in step S20 shown in FIG. 13 is “No” and after performing the control in step S27, step S47 shown in FIG. 15 is performed. Shall return to. Specifically, also in the second embodiment, when the sensor 14 is in the detection state within a period after the spouting water for hand washing and before performing the spouting water after spraying, the spraying water spouting by the second spouting part 13 is performed. Instead, the first water spouting unit 12 performs the foam water spouting, and when the sensor 14 is in the detection state during the after-water spouting, the second water spouting unit 13 stops the spray water spouting and the first water spouting. Foam water is discharged by the unit 12.

(Operation and effect of the second embodiment)
Next, the function and effect of the automatic faucet device according to the second embodiment of the present invention will be described. Here, only the operation and effect different from the above-described first embodiment will be described.

According to the second embodiment, while the sensor 14 is detecting the object to be detected, the spray water is first sprayed from the second water discharger 13 and a predetermined time T5 (for example, 3 seconds) from the start of the spray water discharge. ) Has elapsed, the spray spouting is stopped and the foam spouting is performed from the first spouting portion 12. Therefore, first, the hand washing can be efficiently performed using the spray spouting with a small flow rate but a high flow rate, After that, not only hand washing but also face washing and water storage can be efficiently performed by using a large amount of foam spouted water. Therefore, it is possible to save water appropriately while ensuring the convenience of the user. In particular, according to the second embodiment, since foam spouting is automatically switched after spraying spouting water, it is possible to perform operations other than hand washing (face washing, water storage, etc.), or for a relatively long time such as hand washing with soap. High convenience is ensured because the user automatically switches to foam spouting without any special operation or awareness by the user when performing an operation.

Further, according to the second embodiment, after the spray water discharge from the second water discharge part 13 is stopped, the foam water discharge from the first water discharge part 12 is performed after a certain time (for example, 0.5 seconds). That is, since the water is temporarily stopped between the spray water discharge and the foam water discharge, the user can be notified of the end of the spray water discharge. As a result, the user can be given an opportunity to stop hand washing and the like, and it becomes possible to save water effectively.

Further, according to the second embodiment, the predetermined time T5 for spraying water is changed in the hand-washing water discharge, so that it is convenient for the user and saves water depending on the usage environment of the automatic faucet device 1. Depending on which is given priority, the predetermined time T5 for spraying water can be adjusted appropriately. For example, in an environment in which dirt that is hard to remove adheres to the hand and requires relatively long hand washing, the predetermined time T5 for spraying water may be shortened to prioritize user convenience over water saving. it can.

Further, according to the second embodiment, the sensor 14 does not detect the detected object, and the sensor 14 detects the detected object until the predetermined time T1 (for example, 3 seconds) elapses after stopping the hand washing water discharge. When it is detected, instead of spraying water from the second water discharger 13 again, foam water is discharged from the first water discharger 12, so that the convenience of the user can be appropriately secured. .. For example, when the user tries to draw water with his/her hand or wash his/her hand with soap after moving his/her hand out of the detection range of the sensor 14 during hand washing, instead of spraying water, foam is generated. Since water is discharged, the convenience for the user can be secured.

<Modification>
Next, a modified example of the above-described embodiment will be described. The modified examples described below can be applied to the above-described embodiment by appropriately combining them.

(Modification 1)
In the above-described embodiment, the foam water discharge is performed from the first water discharge part 12, that is, the foam water discharge is shown as the first water discharge mode in the present invention, but the foam water discharge is performed as the first water discharge mode in the present invention. Is not limited to applying. As a first water discharge mode in the present invention, shower water discharge is performed in which water is discharged in a shower form from a large number of water discharge ports having a small diameter, or water is linearly discharged from one or more water discharge ports having a relatively large diameter. It is possible to apply various water spouting forms such as straight water spouting (strictly speaking, the foam spouting water shown in the above-described embodiment is included in this straight water spouting) or a water spouting form in which foam water spouting and shower water spouting are combined. is there.
Further, the first water discharge form and the second water discharge form are not limited to different forms of discharging the fluid from the water discharge part (foam water discharge, spray water discharge, etc.), and the fluid is discharged from the water discharge part. Instead of changing the form to be performed, the type of fluid discharged from the water discharge part may be changed. For example, a form in which normal water is discharged from the water discharge part may be applied as the first water discharge form, and a form in which electrolytic water is discharged from the water discharge part may be applied as the second water discharge form. Alternatively, a form in which electrolytic water is discharged from the water discharge unit may be applied as the first water discharge form, and a form in which normal water is discharged from the water discharge unit may be applied as the second water discharge form. In addition, both the first water discharge form and the second water discharge form are applied with the form in which the electrolytic water is discharged from the water discharge part, and the concentration of the electrolytic water applied to the first water discharge form and the second The concentration of electrolyzed water applied to the water discharge form may be different.
Further, the first water discharge form and the second water discharge form differ in the form in which the fluid is discharged from the water discharge part (foam water discharge, spray water discharge, etc.), and the type of fluid discharged from the water discharge part (normal water Alternatively, electrolyzed water) may be different.
When such a modified example is applied, the following examples of water discharge forms can be considered. In the first example, normal water can be sprayed and spouted for handwash spouting, and electrolytic water can be sprayed and spouted for after-spraying. In the second example, normal water can be foamed and spouted in hand-washing water, and electrolytic water can be foamed and spouted in after-water spouting. In the third example, in spout water for hand washing, after spraying electrolytic water, normal water is foamed and discharged, and in after-water discharge, electrolytic water can be sprayed and sprinkled. In the above-described second embodiment, in the spouting water for hand washing, the normal water is sprayed and spouted, and then the normal water is spouted and the electrolytic water is sprayed and spouted in the after spouting.

(Modification 2)
In the above-described embodiment, after-water discharge is performed using electrolyzed water, but after-water discharge may be performed using normal water instead of using electrolyzed water. In that case, the electrolytic bath 37 may not be provided on the second flow path 18. Even after such after-water discharge using normal water, it is possible to prevent the dirt flowing out by hand washing from drying and adhering to the bowl 3 of the hand washing device 5 or the like.

(Modification 3)
In the above-described embodiment, the two solenoid valves, the first solenoid valve 25 and the second solenoid valve 28, are used to switch between the water discharge from the first water discharge part 12 and the water discharge from the second water discharge part 13. However, the water discharge from the first water discharger 12 and the water discharge from the second water discharger 13 may be switched using only one solenoid valve.

With reference to FIG. 16, the functional configuration of the automatic faucet device according to the third modification of the embodiment of the present invention using only one solenoid valve will be described. FIG. 16 is a block diagram schematically showing a functional configuration of an automatic faucet device according to Modification 3 in the embodiment of the present invention. Here, the same components as those of the automatic faucet device 1 shown in FIG. 6 are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 16, the automatic faucet device 1a according to Modification 3 has a solenoid valve 51 and a switching valve 52 instead of the first solenoid valve 25 and the second solenoid valve 28. The configuration is different from the automatic faucet device 1 shown. The solenoid valve 51 is provided on the common flow path 21, and opens and closes under the control of the controller 40 to switch between normal water flow and cutoff in the common flow path 21. The switching valve 52 is provided at a connection point between the common flow channel 21 and the first flow channel 17 and the second flow channel 18, in other words, at a branch point at the downstream end of the common flow channel 21. The switching valve 52 operates under the control of the controller 40, and switches the flow path of the normal water to either the first flow path 17 or the second flow path 18.

The switching valve 52 described above is configured as an electric valve controlled by the controller 40, but instead of such a switching valve 52, a mechanical valve driven by water pressure is applied as the switching valve. You may. When a switching valve as a mechanical valve is applied, the opening of a solenoid valve 51 provided on the common flow path 21 upstream of this switching valve is adjusted to adjust the water pressure applied to the switching valve. By doing so, the flow path through which the normal water flows may be switched between the first flow path 17 and the second flow path 18.

(Modification 4)
In the above-described embodiment, after the spout for hand washing, after-water spouting is performed after a predetermined time has passed (see FIG. 7, FIG. 14, etc.), but in another example, after the spout for hand washing is stopped, The after-water discharge may be performed without leaving the space, that is, the after-water discharge may be performed continuously with the hand-wash water discharge.
In still another example, after-water discharge may be started during the execution of hand-wash water discharge so that the after-water discharge overlaps the hand-wash water discharge. In that case, while the sensor 14 is in the detection state, spouting water for hand washing is performed. When the sensor 14 is switched from the detection state to the non-detection state, after-water spouting is started while continuing spouting water for hand washing The end time of spouting water for use and the start time of spouting after water may be overlapped. However, it is assumed that the hand-washing water discharge is stopped before the after-water discharge water, in other words, the after-water discharge is stopped after the hand-washing water discharge is stopped.

(Modification 5)
In the automatic faucet device 1 according to the above-described embodiment, the two water discharge portions (the first water discharge portion 12 and the second water discharge portion 12) are used by using the two flow passages (the first flow passage 17 and the second flow passage 18). Water discharge (foam water discharge and spray water discharge) was performed from the water discharge unit 13) in two forms. Specifically, in the first embodiment, foam water is discharged from the first water discharge part 12 through the first flow path 17 as hand-wash water, and as after-water discharge through the second flow path 18. The spray water was discharged from the second water discharger 13 (see FIG. 7, etc.). In another example, only one flow path and one water discharge part may be used to perform both the hand-wash water discharge and the after-water discharge by one type of water discharge. Specifically, in another example, only the water spouting unit capable of spraying and spouting is used to perform both hand-washing spouting water and after-spraying water.

With reference to FIG. 17, a configuration of an automatic faucet device according to a modified example 5 of the embodiment of the present invention, which performs both hand-washing water discharge and after-water discharge only by spraying water will be described. FIG. 17(A) is a perspective view of an automatic faucet device according to a modified example 5 of the embodiment of the present invention as seen obliquely from below, and FIG. 17(B) shows the automatic faucet device of FIG. 17(A). FIG. 6 is a sectional view taken along line XVIIB-XVIIB in FIG.
In addition, below, the same code|symbol is attached about the same component as the component (refer FIG. 2) of the automatic faucet apparatus 1 by the above-mentioned embodiment, and those description shall be abbreviate|omitted suitably. That is, the components that are not particularly described here are similar to those of the automatic faucet device 1.

As shown in FIGS. 17(A) and 17(B), the automatic faucet device 1b according to Modification 5 does not include the first water discharger 12 and the first flow path 17 for performing foam water discharge, The configuration is different from the automatic faucet device 1 according to the above-described embodiment in that only the second water discharger 13 and the second flow path 18 for performing spray water discharge are provided. The other configuration is almost the same as the automatic faucet device 1 according to the embodiment. Specifically, the automatic faucet device 1b according to the fifth modification also has a sensor 14 for detecting an object to be detected and an LED 15 for irradiating light, like the automatic faucet device 1 according to the embodiment.
In addition, in the automatic faucet device 1b according to the modified example 5, the phrase "second" is attached to the "second water discharge part 13" and the "second flow path 18", which means "first". It is not based on the premise that the water spouting section and the flow path are present, but is because it has the same configuration as the second water spouting section 13 and the second flow path 18 of the automatic faucet device 1 according to the above-described embodiment. ..

Next, with reference to FIG. 18, a functional configuration of the automatic faucet device 1b according to the modified example 5 of the embodiment of the present invention will be described. FIG. 18 is a block diagram schematically showing a functional configuration of an automatic faucet device 1b according to a modified example 5 of the embodiment of the present invention. Here, the same components as those of the automatic faucet device 1 shown in FIG. 6 are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 18, the automatic faucet device 1b according to Modification 5 does not include the first water discharge part 12, the first flow path 17, and the first electromagnetic valve 25, and thus the automatic water faucet device 1b according to the above-described embodiment is not provided. The configuration is different from that of the faucet device 1. In the automatic faucet device 1b according to Modification Example 5, the controller 40 controls the opening/closing of the second electromagnetic valve 28 (the reason why the word “second” is attached is as described above). The spray water discharge from the second water discharger 13 via the second flow path 18 is switched on/off.

Next, with reference to FIG. 19, a control according to the modified example 5 of the embodiment of the present invention will be described. FIG. 19 is a time chart showing the control according to the modified example 5 of the embodiment of the present invention. FIG. 19 shows, in order from the top, the sensor signal supplied from the sensor 14 to the controller 40, the drive signal supplied from the controller 40 to the second electromagnetic valve 28, the drive signal supplied from the controller 40 to the electrolytic bath 37, and the controller. The drive signal supplied from 40 to the LED 15 is shown.

First, at time t61, the sensor signal switches from off to on, that is, the sensor 14 switches from the non-detection state to the detection state. At this time, the controller 40 energizes the second electromagnetic valve 28 to open the second electromagnetic valve 28, and causes the second water discharger 13 to spray normal water. Then, at time t62, the sensor signal switches from on to off, that is, the sensor 14 switches from the detection state to the non-detection state. At this time, the controller 40 stops energizing the second electromagnetic valve 28 and closes the second electromagnetic valve 28 to end the foam water discharge from the second water discharger 13, that is, the water discharge for hand washing. To finish.

After that, when the non-detection state of the sensor 14 continues for a predetermined time T1 from the time t62 when the spray water discharge as the hand-wash water discharge is completed, the controller 40 causes the second water discharge unit 13 to perform the spray water discharge again. Specifically, the controller 40 first turns on the LED 15 at a time t63, and at a time t64 immediately after this time t63 (corresponding to a time after a predetermined time T1 has elapsed from the time t62 at which the water spout for hand washing is finished). , The second solenoid valve 28 is energized to open the second solenoid valve 28. Then, at time t65 immediately after this time t64, the controller 40 energizes the electrolytic bath 37 to generate electrolytic water in the electrolytic bath 37, thereby spraying the electrolytic water from the second water discharger 13. That is, after-water discharge is performed.

After that, at a time t66 when a predetermined time T3 (for example, 1.9 seconds) has elapsed from the time t64 when the second electromagnetic valve 28 is opened, the controller 40 stops energizing the electrolysis tank 37 and causes the electrolysis tank 37 to stop. The production of electrolyzed water at 37 is terminated. At this time, since the second electromagnetic valve 28 is still open, the spray water discharge from the second water discharge portion 13 is continued. Then, at a time t67 after the time t66, specifically, at a time t67 when a predetermined time T2 (for example, 3.5 seconds) has elapsed from the time t64 when the second electromagnetic valve 28 is opened, the controller 40 causes the LED 15 to operate. Is turned off to end the irradiation of the light from the LED 15, and the second solenoid valve 28 is closed by stopping the energization of the second solenoid valve 28, thereby spraying from the second water discharger 13. The water discharge is ended, that is, the after water discharge is ended.

According to the modified example 5 described above, the hand-washing water discharge is performed by the spray water discharge when the sensor 14 is in the detection state, and the hand-wash water discharge is ended when the sensor 14 is in the non-detection state, and the after-water discharge is performed by the spray water discharge after that. As a result, the after-water discharge can be appropriately performed when there is a possibility that the dirt flowing out by the hand-washing using the hand-washing water may be dried and adhered to the bowl 3 of the hand-washing device 5 etc. It is possible to prevent such stains from being dried and adhered to the bowl 3 or the like of the hand washing device 5 while suppressing such spouting. Therefore, the bowl 3 and the like of the hand washing device 5 can be kept clean.

In Modification 5 described above, spout water for hand washing by spray spouting using normal water and after-water spouting by spray spouting using electrolyzed water are performed, but the present invention is not limited to this, and other than this. Also, the following modifications are possible. As a first modified example, water spouting for hand washing by spray spouting using normal water and after-water spouting by spray spouting using normal water may be performed. As a second modification, water spouting for hand washing by spray spouting using electrolyzed water and after-water spouting by spray spouting using normal water may be performed. As a third modified example, water spouting for hand washing by spray spouting using electrolyzed water and after-water spouting by spray spouting using electrolyzed water may be performed. In the third modified example, the concentration of the electrolyzed water may be different between the electrolyzed water used for hand-washing spouted water and the electrolyzed water used for after-spraying water.
